WILLIAM H. LLOYD, OF BOSTON, MASSACHUSETTS, ASSIGNOR TO THE J. L. MOTT IRON WORKS; OF NEIV YORK, N. Y., A CORPORATION OF NEW YORK.

WATER-CLOSET.

SPECIFICATION forming part of Letters Patent No; 689,679, dated December 24, 1901.

Application filed September 25,

To all whom it may concern:

Be it known that I, WILLIAM H; LLOYD, a citizen of the United States, residing at Boston, in the county of Suffolk and State of Massachusetts, have invented a new and useful Improvement in Water-Closets, of which the following is a specification.

My invention relates to the upper portion of the closet, and particularly to the arrangement of the vent in connection with the inlet-chamber for flushing-water. In carrying out my invention the vent comprises two openings from the bowl below the flushingrim and two connecting ventilating-passages extending rearward from said openings at the sides and around beneath the inlet-chamber for flushing-water and extending, preferably, slightly upward, the said ventilating passages having one mouth or opening at the rear of the closet and above the'horizontal plane or level of the flushing-rim and to which a separate vent-pipe may be connected, thus preventing an overflow of the bowl discharging into the vent-pipe. These parts are above and disconnected from the crown of the leg or trap, so that there is a clear way at the outside of the closet between said parts and the crown of the legor trap, the said parts beingin no sense supported by the leg or trap. The bowl of the closet has made integral with it the ventilating-passages at each side of and beneath the inlet-chamber for flushing-water, which passage-ways terminate in the two openings through the wall of the bowl at one end and in the one opening or mouth at the other end, and I prefer to make these passage-ways and the inlet-chamber for flushingwater integral and of one piece of porcelain with the bowl and to perforate the wall between the chamber for flushing-water and the ventilating-passages. I may, however, employ an additional piece rising from the mouth of the ventilating passage-ways, and I may pass down through this a pipe to join with the inlet-chamber for flushing-water.

In the drawings, Figure 1 is a vertical 1ongitudinal section and partial elevation representing the most improved form of my'invention, and Fig. 2 is an elevation looking rearward from within the bowl. Fig. 3 is a vertical longitudinal section and partial eleva 1399. SerialNo. 731,522. (Nomodel-l tion'representing a form of my invention, and Fig. 4 is a sectional'pla'n at 0a m of Fig. 3.

, 0. represents the bowl or hopper of the closet, and a the flushing-rim.

1) represents the inlet-chamber for flushingwater,ad apted at its upper end for connection with a pipe and opening at its lower end directly into the flushing-rim. "The ventilating-passages c c extend along the two opposite sides of and beneath the inlet-chamberb for flushing-water. At one end they are provided with the adjacent openings 2 and 3 through the wall of the bowl of the-closet below the flushing-rim, and at the other end they come together and join in the mouth or opening 4, at which point an independent pipe may be connected. These parts I prefor to form integral and of one piece of porcelain with the bowl and the leg or trap of the closet, but do not limit'my invention in this respect. They, however, are separate and independent from said leg or trap and are in no sense supported upon the crown thereof.

In the form of my invention shown in Figs. 3 and 4 I prefer to employ a curved end 5, turning the passage-way from the horizontal plane of the opening 4 above the plane of the top of the bowl to an opening in a vertical plane, at which opening an outside pipe is adapted to be connected, and this end 5 has a flange setting into the mouth or opening .4. In connection with the curved end 5 I pass down through the same a pipe 6 for supplying flushingwater connected to the couplingpipes 7 and 8, entering the open back of the flushing-rim. The part 9 in the drawings represents the wall of the bowl, forming a par tition between the respective openings into the bowl from the said ventilating-passage. This partition may be of any desired'size or extent and acts as a support to the upper part of the closet from the bowl.

The ventilating-passages c c in extending rearward from the bowl extend slightly upward, andthe mouth 4, formed by the union thereof, is above the horizontal plane of the top of the flushing-rim or bowl to prevent any overflow of water from the closet discharging into the vent-pipe. I prefer to make a number of perforations 10 through the wall of the closet between the inlet-chamber for flushingwater and the ventilating-passages to allow the escape of a small quantity of water into the ventilating-passages and thence into the closet to insure a cleanly condition.

I claim as my invention 1. Awater-closet bowl comprising in a single piece or structure of porcelain a flushingrim,an inlet connecting-chamber for flushingwater extending rearward therefrom, ventilatingpassages at either side of the inletchamber for flushing-water and provided at one end with adjacent openings into the bowl of the closet below the flushing-rim, said ventilating-passages joining at the other end into a single mouth or opening at the rear of the closet and said parts being free of and disconnected from the crown of the leg or trap, substantially as set forth.
